Hot drawing is the heating before the wire enters the die hole, mainly used for high melting point wire drawing; The temperature drawing is carried out by heating the heater to the range of temperature, mainly used for galvanized steel wire, difficult to deform drawing.

Because of its light weight, strength is relatively large has gradually begun to replace the original column. At the same time, due to the relatively uniform specifications, the barbed rope installation is also more beautiful. The direct spacing of the barbed rope is relatively fixed, which can effectively prevent crossing. At the same time, the mesh at the bottom is relatively dense, while the mesh at the top is relatively loose, which can save resources.

Dog cage mainly by welding, spraying, injection molding, surface treatment, electroplating dog cage is made of high quality steel wire, dog cages are with plastic and plastic surface treatment, electrophoresis, chrome plating, galvanized, imitation gold, etc., according to the customer request processing, respectively, also can be customized to sample, dog cage assembly of compact structure, neat and beautiful appearance, make folding and remove the cage is more convenient and quick, won’t take up too much space.

Nestor rolling cage, high-speed railway Nestor rolling cage and railway Nestor rolling cage are all produced, sold and installed in accordance with the technical requirements of the reference drawing of railway line 2012-8001. Nestor rolling cage is a kind of protective equipment emerging in railway in recent years. Nestor rolling cage is connected by Nestor connecting clip on the longitudinal tensile rib fixed on the bracket. The longitudinal tension and the support are connected with the Φ2.5mm cold-drawn galvanized steel wire around 2 laps and then tightened. The support is set in the column and the middle of the span of the protective fence of 3m. The other spans are only set with the upper column, and the support and the protective fence are connected with the bracket hoop. For the protective fence that has been installed with metal mesh, the Nestor roller cage is directly fixed on the transverse sheet and wire of the metal mesh with the cold-drawn galvanized steel wire of 2.5mm or the Nestor connection fastener.

In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The specific use of how much wire and silk need to go through a series of professional measurement but also increase the loss of raw materials and other factors to calculate. Thorn rope factory will also according to customer needs to calculate the reasonable amount of customer use.

Some large roll galvanized wire products in order to meet different industrial needs, will be further processed on the surface, such as the anti-corrosion layer, galvanized, iron plating, aluminum alloy plating, or in the galvanized wire appearance above the copper plating, brass plating, etc., to strengthen the steel wire and colloidal years and capabilities. Generally, galvanized wire products should be well plated and drawn when they are produced, and the sequence of the two processes should be decided according to the production or industrial needs.

Although galvanized iron wire has the protection of galvanized layer, it does not say that it will not rust at all, but delays the time of rust. In general, cold galvanized iron wire can be kept for 1-2 years without rust, hot galvanized iron wire can be used for 8-10 years without rust. If properly maintained, the use time will be longer. So how to prevent galvanized iron wire rust?

Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it is also necessary to conduct reasonable post-processing to avoid affecting its use effect. Of course, when the black iron wire is galvanized, it is also necessary to ensure the thickness of the galvanized layer, so that it can also reduce the possibility of rust. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
